Can ultrasound fight Alzheimer's? Mice study hints at new weapon

LONDON (Reuters) - Scientists believe they may have found a new weapon in the fight against Alzheimer's disease -- not in the form of a drug but in focused beams of ultrasound.

While the approach has only been tested in mice, researchers said on Wednesday it proved surprisingly good at clearing tangles of plaques linked to Alzheimer's in the animals' brains and improving their memory, as measured by tests such as navigating a maze.
